Specification of Letters Patent.

Patented July 1s, 1911.

Application filed May 14, 1906. Serial No. 316,615.,

To all whom it may concern:

Be it known that I, GEORGE NEUFELD, of Philadelphia, county ofPhiladelphia, and State of Pennsylvania, have invented certain new anduseful Improvements in Bobbin-Carriers; and I do hereby declare thefollowing specification, taken in connection with the accompanyingdrawings, forming a part of the same, to be a full, clear, and exactdescription thereof.

The invention relates to bobbin-carriers for braiding machines, and hasfor its object to provide a structure in which the bobbin may be readilyapplied and removed and in which the sliding pawl and tension weight maylikewise be readily removed and replaced, but will also be held againstaccidental displacement in the working of the machine.

One feature of invention consists in provinding a hinged spindle for thebobbin, with means for normally holding the spindle and bobbin in propervertical position, the construction being such that the bobbin andspindle may be tipped to one side, and so that an empty bobbin may beremoved from the spindle and a new bobbin placed thereon.

A further feature of invention consists in providing a detachablethread-guide which in its normal position will serve to prevent theremoval or displacement of the sliding pawl and tension weight, butwhich may be readily detached from the carrier and so as to permit theremoval of said tension weight and pawl when it is desired to substituteothers therefor.

The invention further consists in certain features of constructionhereinafter described and claimed.

Referring to the drawings, Figure l represents in side elevation abobbin-carrier embodying the invention with a bobbin in place therein;Fig. 2 is a corresponding view showing the bobbin and spindle tipped toone side to permit the bobbin to be removed from the spindle; Figs. 3, 4and 5 are detail views to be hereinafter referred to.

In the drawings 1 represents the base of the carrier provided with theusual groove 2 for engaging the raceway of the braiding machine and thestud 3 by which the carrier is moved by its operative devices.Projecting upward from the base 1 is the tension weight standard tprovided at its upper end with a horizontal arm 5. Also projectingupward from the base 1 is a short standard 6 in which the spindle 7 ispivoted or hinged. In the construction shown in the drawings thisstandard 6 is provided with a vertical slot, and the lower end of thespindle is made fiat so as to enter this slot, and

is connected to the ears of the standard formed by said slot by a pivotor hinge-pin 8. The lower end of the spindle is located somewhat abovethe lower end of the slot in the standard, as indicated in dotted linesin Fig. l, so as to permit the necessary tipping of the spindle. Theouter corner of the flattened lower end of the spindle, which ispreferably extended somewhat to form a toe 9, constitutes a stop tolimit the extent to which the spindle may tip, as shown in Fig. 2.

The upper end of the spindle is provided with a slot 10 to form springfingers l1, as shown in Fig. 3, and the outer end of the horizontal arm5 is forked and provided with an opening 12, as shown in Fig. 4f, toreceive the spring fingers 11 formed at the upper end of the spindle.The fingers 13 at the forked end of the arm 5 are constructedsubstantially as shown in Fig. 4:, that is, are of a wedge-shape attheir outer ends and with the space between said iingers, which formsthe passage leading to the opening 12, less than the diameter of thesplit upper end of the spindle 7. With, this construction when the splitupper end of the spindle is forced between the wedge shaped outer endsof the fingers 13, the spring iingers 11 of the spindle will be pressedtogether, setting up a spring force therein, and so that when saidfingers have passed into the circular opening l2 they will spring apartinto their normal position and so as to be embraced by the fingers 13 ofthe arm V5, and the spindle will be thereby held in its proper verticalposition until a sufficient force is applied to withdraw it from theembrace of the fingers 15. ris will be seen, with the lingers 13 shapedas shown a considerable force will require to be exerted in a` directionto pull the upper end of the spindle out of the opening 12, and thespindle will consequently be held in position against any accidentaldisplacement.

The sliding pawl 14e and the tension weight 15 are of the usualconstruction and are mounted on the standard L1- in the usual manner,the sliding pawl being adapted to engage the ratchet lo formed on theupper end of the bobbin as usual.

l`he thread-guide 17 is in the form of a spring clip adapted to beremovably secured in place on the horizontal arm 5. This thread-guide ispreferably constructed of sheet metal and is forked or slotted to .formspring fingers 18. These lingers 18 are provided at their outer endswith wedge-shaped portions 19, and with a space between them forming acontracted passage leading to an opening Q0 adapted to receive the shankof a headed stud Q1 secured to the horizontal arm Preferably thethread-guide is also provided with side wings or clips 22 which are bentinward and adapted to engage undercut recesses 22 formed in the sides ofthe standard et, as shown in Fig. 6. Atits outer end the thread-guideprovided with the usual guide-eye The thread-guide is placed in positionby sliding the same along the upper surface of the horizontal arm until.the shank of the stud 21 is brought into the opening 20. ln doing thisthe spring-fingers 1S will be forced apart by the engagement of thewedge-shaped portions 19 with the shank of the stud 21, thereby settingup a spring force in said fingers. lWhen the shank of said stud haspassed. into the circular opening 20, the spring fingers will return totheir normal position and so as to substantially embrace said stud.lilith this construction, will be seen, the thread-guide will beremovably held in position against longitudinal displacement by theengagement of the spring fingers 18 with the stud 21, and will likewisebe removably held against vertical displacement by the head of the stud21 and also by the engagement of the wings 22 with the undercut recessesQ3. 1t will be further seen that as long as the thread-guide remains inposition the outer projecting end thereof will constitute a barrieragainst the removal or accidental displacement of the sliding pawl andtension weight. Whenever it is desired to remove said pawl and weightfor the purpose of substituting others or otherwise, all that isnecessary to be done is simply to withd aw and remove the threadguide,when said pawl and weight may be of the standard +l. lVhen the properpawl and weight have been placed upon the standard, the thread-guide isagain slipped into position, and will serve to hold them againstdisplacement.

lt will be observed that with the above construction the bobbin is notsupported between top and bottom bearings, but is instead supported andheld by the spindle 7 which passes through the bobbin, the horizontalarm 5 serving simply to hold the hinged spindle in proper verticalposition.

lVhile l have shown the spindle as provided with spring lingers toengage the forked end of the horizontal arm, it will be understood that,if desired, instead of thus providing the spindle with such springVlingers the lingers 13 of the horizontal arm may be made springlingers, and so as to spring about the upper end of the spindle which insuch case may be made solid.

What l claim as my invention and desire to secure by Letters Patentis:
